Hello Everyone..Just purchased a new Mossberg 500 Persuader. Disassembled, Cleaned, Reassembled. When I dry fired for testing, the trigger allowed for 2 pulls after one pump. The first pull sounded like more of a full click but the second pull still clicked..kinda like the first pull maybe didn't fully drop. Any ideas for what this can be?

Also should mention that I continued to test and got 2 trigger pulls pretty much every time.
